Ladybugs are highly visible throughout Saskatchewan this month before hibernation, as per experts. Georgiana Antochi-Crihan, Saskatoon’s entomologist, explained the current surge in ladybugs as part of natural cycles influenced by food availability. Ladybugs primarily feed on aphids, scale insects, and mealybugs.
While Regina has not experienced a significant ladybug increase, there has been a notable rise in aphids, which support the survival of ladybugs. Similarly, North Battleford saw an abundance of aphids this past summer, attracting ladybugs to the area. Vesna Fa, from Midwest Food Resources, emphasized the importance of preserving ladybugs as beneficial allies in gardens.
Candace Savage, chair of Wild About Saskatoon, highlighted the importance of celebrating the diverse ladybug species in the province and providing habitats for their well-being. Among the 75 ladybug species in Saskatchewan, the seven-spotted lady beetle is a common introduced species identifiable by its seven spots.
As ladybugs prepare for hibernation, they gather in warmer areas, such as the sides of buildings. Their ability to survive the harsh prairie winter is attributed to internal antifreeze compounds they produce. Antochi-Crihan mentioned that ladybugs will likely reemerge in large numbers next spring.
